Description
技术领域
本发明涉及莫来石技术领域,特别是涉及一种高强度莫来石耐火砖。
背景技术
莫来石耐火砖砖以莫来石(3Al2O3·2SiO2)为主晶相的高铝质耐火材料。一般氧化铝含量在65%~75%之间。矿物组成除莫来石外,其中含氧化铝较低者还含有少量玻璃相和方石英;含氧化铝较高者还含有少量刚玉。莫来石耐火砖的耐火度较高,可达1790℃以上。荷重软化开始温度1600~1700℃。常温耐压强度70~260MPa。抗热震性良好。莫来石耐火砖有烧结莫来石砖和电熔莫来石砖两种。烧结莫来石砖以高铝矾土熟料为主要原料,加入少量黏土或生矾土作结合剂,经成型、烧成而制成。电熔莫来石砖以高矾土、工业氧化铝和耐火黏土为原料,加入木炭或焦炭细粒作还原剂,成型后采用还原电熔法来制造。电熔莫来石的结晶比烧结莫来石大,抗热震性比烧结制品好。他们的高温性能主要取决于氧化铝的含量和莫来石相与玻璃分布的均匀性。主要用于热风炉炉顶、高炉炉身和炉底、玻璃熔窑蓄热室、陶瓷烧结窑、石油裂解系统死角炉衬等。
现有的莫来石砖的强度不高,容易断裂。
